Piezoelectric transducers have long dominated ultrasonic transducer technology, but capacitive micro-machined ultrasound transducers (cMUTs) have emerged as an alternative. Features of cMUT devices… (More)

An integrated 90V 16-channel CMOS analog switch array has been designed and fabricated for next generation medical ultrasound systems. The array was implemented in AMIS I2T100 technology; the die… (More)

In this paper, a high voltage 1 to 64 Mux / De-Mux is proposed using a high voltage CMOS process for a high frequency synthetic aperture imaging system. The controlling stage is made up of a low… (More)

High channel count, large area ultrasound arrays at fine pitch require close integration of transducer elements and ASIC electronics. Composites of single crystal material and non-conducting epoxy… (More)

Ultrasound guided needle biopsy is an important method for collection of breast cancer tissue. In this paper, we report on the design and testing of a high voltage 1 to 64 MUX / De-MUX Integrated… (More)
